SharpEye™ 20/20U-UB UV Flame Detector





TThe SharpEye UV Optical Flame Detectors 20/20U and 20/20UB (which includes a BIT function) are designed to meet the strict
industry performance requirements. The UV sensor has been carefully selected to ensure the greatest degree of spectral matching to the radiant energy emissions of fire. Flame is detected typically within 3 sec. for a 1ft.2 (0.1m2) pan gasoline fire. A unique Fast UV Flame Detector Model (20/20FU) detects within several milliseconds a saturated UV signal caused by an
explosion or a large fire.
The microprocessor design allows for unique field programmability making these flame detectors easily adaptable to all environments, applications and requirements.
The SharpEye UV Flame Detector incorporates a special logic circuit that helps prevent false alarms caused by solar radiation.
Both U and UB models are self-contained, optical flame detectors that function as stand-alone units directly connected to external devices such as alarm systems or automatic fire extinguishing systems.
The UV detectors are particularly useful for detection of invisible flames from fuels such as: Hydrogen, Hydrides, Ammonia, Silane and other inorganic fuels.

* It is important to note that this detector must not be exposed to UV radiation sources such as: electrical arcs, sparks and welding, etc
